#3580 — beginner question

I'm trying to plot three dimensional points

splot "cube.txt"

where cube.txt is as follows

0 0 0
0 0 100
0 100 100
0 100 0
0 100 100
100 0 0
100 100 0
100 100 100

the points are okay but the zaxis has two zeroes and a space between 
them, I have set xrange, yrange and zrange and the zaxis remains the same

if I do

plot "square.txt"

where square.txt is as follows

0 0
0 100
100 0
100 100

the x and y axis work as I want


I did a little with autoscale, is this where I need to look?

I get numbered tics at 0,20,40...100 on the x,y and z-axis.

The zero at the intersection of the z-axis with the xy-plane belongs
to the x-axis.

gnuplot> set xrange [0:100]
gnuplot> set yrange [0:100]
gnuplot> set zrange [0:100]
gnuplot> set xtics 0,10,100
gnuplot> set ytics 0,10,100
gnuplot> set ztics 0,10,100
gnuplot> splot "cube.txt"

still two zero planes along z axis

xaxis is now reversed (100 to 0)

found a solution with a websearch of (gnuplot two xy planes in splot)
http://theochem.ki.ku.dk/on_line_docs/gnuplot/gnuplot_36.html

gnuplot> set xyplane 0

but why wouldn't this be the default?

(set ticslevel is deprecated in Version 5.0 patchlevel 5)

thanks much
